-

i trying (very hard) plone version 4.2.4 work correctly. had previous installation removed. attempted reinstall @ later point. seemed fine until couldn't upload pictures , had pulled in data previous install (folders , such). i've tried purge 5 times , fresh install either pulls in data (folders in particular) previous installation or breaks somehow not allowing me upload files etc.

does have suggestions on how combat this? i'm ready ditch plone.
